What must you point out to your pillion passenger before setting off?

You answered correctly. Before setting off with a pillion passenger on a motorcycle, you must inform them that they need to keep their feet on the footrests for safety and stability, and they must wear a safety helmet because it is required by law. These measures help prevent injuries and ensure proper balance of the motorcycle. It is not correct to instruct the passenger to lean to the outside on bends; the passenger should lean with the rider through curves. Remember these basic safety points whenever you carry someone on your motorcycle.
